Abstract
L'invention concerne l'industrie du laminage. Le dispositif faisant l'objet de l'invention est du type comprenant des capteurs de pression hydrauliques 12 sensibles à l'effort de laminage, placés sous les empoises 9 d'au moins l'un 10 des cylindres 3, 10 de la cage 4 et ne subissant pas l'action des vérins hydrauliques 1 assurant la mise de la cage 4 en précontrainte et communiquant avec la cavité desdits capteurs de pression hydrauliques et avec une source 14 de fluide à pression constante, et est caractérisé en ce que chacun desdits vérins hydrauliques comporte deux chambres dont l'une B communique directement avec la cavité 16 du capteur de pression hydraulique 12 correspondant, et l'autre, directement avec ladite source de fluide à pression constante. L'invention s'applique notamment aux laminoirs à tôles et à bandes.The invention relates to the rolling industry. The device forming the subject of the invention is of the type comprising hydraulic pressure sensors 12 sensitive to the rolling force, placed under the chocks 9 of at least one of the rolls 3, 10 of the stand 4 and not undergoing the action of the hydraulic jacks 1 ensuring the placing of the cage 4 in prestressing and communicating with the cavity of said hydraulic pressure sensors and with a source 14 of fluid at constant pressure, and is characterized in that each of said jacks hydraulic comprises two chambers, one of which B communicates directly with the cavity 16 of the corresponding hydraulic pressure sensor 12, and the other directly with said source of fluid at constant pressure. The invention applies in particular to sheet and strip rolling mills.
